YPlus & Turbulance

November 16, 2002, 01:07

Hello, I have three questions, can any body please answer it.

1. How to select the inlet turbulence parameters like dissipation length scale & turbulence intensity in a standard Turbulence modal and, How to verify after the solution that whatever values we have chosen are correct.

2. In case of external flows, what are the parameters to be checked to say that the solution has converged?

3. What is the physical meaning of YPlus and its significance? If it is the input parameter for the software then how it should be chosen

Your answers are most welcome Irfan
